VEHICLE-RIM.

T o all whom t may concern.'

Beit known that I, CHARLES B. KEENUM, a citizen of the United States,residing at Cleveland, inthe county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Vehicle-Rims, of whichthe following isa specification.

This invention relates to vehicle,y rims `of the collapsible type and isan improvement upon the rim of my prior application, Serial No.278,604,1i1ed Feb.24,1919.

The object of the present invention 1s to improve the generalconstruction and arrangement of the hinge members and other operatingparts so as to simplify the rim and provide a flat or shallow form ofmechanism on the inside of the rim that will readily go on the wheelfelly. Another object is to provide abutting relation between the endportion of the hinge and connecting plates and of said plates with therim members to more solidly resist compressing strains on the rim.

Further objects of the invention are in part obvious and in part willappear more in detail hereinafter. j

The invention comprises the construction and arrangement of partshereinafter described and claimed.

Tn the drawings which represent one suitable embodiment of theinvention, Figure 1 is a central sectional elevation on the line 1 1,Fig. 2; Fig. 2 is a plan view of the rim joint viewed in the directionof the arrows 2-2, Fig. 1;. Fig. 3 is a side'elevation of the rim joint;Figs. 4, 5, 6 and 7 are cross sectional views on the lines 4 4, 5 5, 66,

showing the rim collapsed; Fig. 9 is a detail perspective view of oneend portion of a plate; and Fig. 10 is a similar view of a block.

The rim shown in the drawings is an annulusof channel form in crosssection, as shown in Fig. 7, being provided with a tire seat or rim basel and twoopposite flanges or walls'2. On its inner face saidrim isprovided with the usual beveled ribs 3 one of which seats on the wheelfelly and the other of which receives the usual wedging rinfr (notshown).

ne portion of the rim annulus, inthe form, of a relatively `shortcollapsing seg- `ment 4, is separate from the remainder of the annulusand is the portion which is removed or taken out from the annulus toSpecification of Letters Patent.

shorten the same and permit it to collapse or be collapsed -and therebyremoved from the tire. This member 4 has the ribs 3 omitted therefromand on its inner face is' provided with a hinge plate 5, riveted orotherwise secured thereto, whose side edges are beveled, as at 6, incontinuation of the beveled faces of ribs 3. Plate 5` at each end isnotched or recessed, as at 7, but a small metal bridge or cross piece 8is left connectmg the arms 9 on either side of said recesses, sa1dbridge or cross pieces forming hinge pins, as will later a pear.

At one end of sa1d plate 5 the arms 9 eX- tend beyond its end andoverlie a portion of the adjoining rim member 10 where they abut theends of the ribs 3. Between said ribs member 10 is provided with a block11 having a recess or opening 12 to receive the hinge pin 8. This blockis laid in place over the hinge pin and while held in proper position isriveted or spot-welded in place to secure the parts permanently inposition. This arrangement provides a hinge connec- 10, permitting theparts to be moved to f eitherthe full line or dotted line position,

t its other end plate 5 is connected to a toggle bar 13 similar in formto the plate 5 except that at one end bar 13 has a tongue 14 that entersthe recess in plate 5, said tongue having a transverse opening tovreceive the pin 8. This tongue may be formed by a projecting portion ofthe plate 13 and a small plate 15 integral with or secured to the innerface thereof and which small plate enters opening 16 in the tire seat orrim base and prevents relative lateral motion of the parts when the rimis expanded.

The body of bar 13 is beveled at its edgesT as at 13a, and at one endabuts the arms 9 of plate 5, while at its other end it abuts the ribs 3and is pivota'lly connected to a block 17 in the same manner that theplate 5 is connected to block 11.

The rim may consist of two segments, towit, segment 4 and anothersegment which includes the remainder of the rim, in which case when thesegment 4 is collapsed inwardly, as in dotted lines Fig. 1, the othersegment collapses by an inward bending movement. In the drawings thisinward collapsing movement is accentuated by pro` joint directlyopposite the collapsing segment.. This hinge joint comprises a shortplate 17n attached to one segment, say segment 10, and pivotallyconnected to a block 18 attached to the other segment 19.V This hingejoint is in all particulars like the one joining the plate 5 and segmentl0. The construction described enables the rim to be easily collapsed orexpanded and readily adapts it for attachment to the felly. The depth ofthe hinge members is nowhere an ater than the depth of ribs 3.

at I claim is: y

1. A vehicle rim comprising an annulus of channel form in cross sectionprovided with beveledribs on its inner surface, said annulus having onesegmental portion separate and adapted to collapse inwardly, and hingemembers connecting said segment to the remainder of the annulus andprovided with intertting tongues and recesses, said hinge members havingbeveled side ortions which at their ends abut said beve ed ribs.

2. A vehicle lrim comprising an annulus of channel form in cross sectionwith beveled ribs on its inner sur ace, said annulus having onesegmental portion separate and adapted to collapse inwardly, a

rovided plate attached to the inner surface of said collapsing segmentand having beveled side portions which at one end abut the beveled ribsof the adjoining segment and are hinged to said segment, and a togglebar hinged to -the other end of said plate and atA its opposite endabutting the beveled ribs of the adjoining segment and hinged to saidsegment,

said bar also having beveled side portions.

In testimony whereof I aliix my signature.
